Transformation of 4 vectors

  1. I can't understand what the following question asking, can anyone explain it to me?
    Q1 Find the law of transformation under Lorentz transformations of an anti-symmeric 4-tensor.
    "What is the law of transformation means?"

    Q2 Find the special relativistic law of the composition of the velocities by using the Lorentz transformation properties of the 4-velocity.
    "Does it mean that I have to give out the components of velocity or else? "

    Please help me!!
